As /var/run/NetworkManager/resolv.conf still exists after stop, it would be OK. But if the machine is then rebooted with network-manager still disabled, the problem resurfaces. Question: If the symlink is reverted to an empty file on stop, but the /var/run version is kept intact, would NM pick it up again on restart, just by recreating the symlink? Or does NM recreate the /var/run version on startup anyway? If either of these are the case, then it seems that it would be fine to revert /etc/resolv.conf on stop, as it should have no bad effects (and possibly some good ones). Incidentally, it seems as though NM obliterates any previously existing resolv.conf when it is first run, so there is no hope of reinstating the previous version. This does not seem ideal, either. Best wishes, and thanks for your quick response. Julian

Sure, "$(readlink /etc/resolv.conf)" = /var/run/NetworkManager/resolv.conf would be the test -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? signature.asc Description: OpenPGP digital signature

On remove/purge yes, it makes sense to turn it back into a real file (I'll probably just make it an empty one), since other tools expect it to be a file and behave differently if it's a symlink.
